Letten; Patent. Patented Jan. 12, 1909.

To all whom 'it may concm: h Beit known that I, GEORGE B. RINEHART, a citizen of the United States, and a resident of Ashland, in the county of Ashland and State of Virisconsin, have invented a new and Improved Battery-Plate, o\f which the following is a full, clear, and exact desciiption.

- y invention relates-to battery plates, my more particular ob'ect being to produce a type og plate suitab e for use in storage batteries, and perhaps in some instances 1n dry batteries, the arrangement of-the plate being al in place. Reference is 'to be had to the accompanying drawin forming a part of this specification, in w ichdrawings like characters of reference indicate like parts throughout the views, .and in which- 1 is/i front .elevation of a grid forming .the base of the plate, this view showing Qllimmyljete face of the id; Fig. 2 is a rear elevation of the grid; 3 is an enlar .fragmentary eevation of t e lower 'left .and corner of the grid; Fig. 4 is an /nlar'ged entary elevation of the lower right hand corner of the grid; Fig. 5 is a vertical cross section n the line 5 5 of.

Fig. 1,1ookinglin the direction of the arrow, an showing ow the front and back bars are xpaced relatively touch other and staggere for tho'purpose of retaining the active material, and Fig. 6 is a section upon 'the line 6-,-6 of Fig. 3, looking in the direction. of the arrow and showing the vertical compartments to be filled with active material, and showing the s aces whereby this active material 1s filled) intermediate the bars 9 and 10, this view further showing shoulders for holding the active material within the vertical compartments. The grid may, as usual, be constructed o'f 'lead or other appro riate substance, and the active material u may-.be a compound of lead or an other material suitable for the purpose. e rim 7 is provided with an upwardly-extending tang 8 of suihcent size to aford a proper degree of strength. The rim 7 is continued at 82 md at 8h and is-integral with the 8. Front and back bara 9, 10 extend horizontally from one edge to anothet` of the y id, and are stag ered as from Fig. 5. ertical' each other and are connected to ether by smaller bars 11" (see Fig. 6), al of these parts being integral. Intermediate the bars 11-are longitudinal compartments 12 dis osed vertically and extending practicall om the top to the bottom of the Shoulders 14, 15 bound the compartments 12, and increase the stability of the material contained within these compartments.

My invention is used as follows: The grid being cast in one iece and having the conformation above diiscribed,4 the active material is filled into the vertical compartments 12 and is also lled into the spaces intermediate the ,front and back bars 9,10. Being thus arranged, as may be understood from Fig. u, some portions of the active material are staggered relatively to the otherrial is integrally connected together. The shoulders 14, 15 serve effectively to liold portions, and yet all of the active matel firmly in position the activeumateriul filled into the vertical comparti'eiits 12, and to prevent any-accidental movement of this material or any buckling of any part of the grid 1s being charged or 80 material while the discharged. The construction above described resents the followin advantgesto wit: he`ac` tive materia is not readily disen a from the grid and, therefore, cannot ge oosened or caused to fall from the same. The in` ternal resistance ofthe battery plate is re# duced to a minimum and theeiiiciency is proportionately increased. The grid is nnable to disintegrate, and can stand under heavier charges and dischar es of the current. The exposed surface o the grid is increased, there being in effect four surfaces. Crinkling and buckling being prevented, 'the grid retains its general conformation /better than in other grids.

Havi thus described my invention, what Irzlzlgaim as new and desire to secure by Letters Patent is:

A battery grid comprisin a rim pro` vided with an integral ta ront horizontal bars arranged in space relation within the rim, and back horizontal bars arranged in spaced relation within the rim, and spaced -apart from the front bars, and sta red wlth respect thereto, and verti y isposed bars arranged within the rim, and

bar s 11, 11 are disposed in alinement .with

between the front and the back bars, 'and having a depth substantially equal to that of l naine (o this specification in the presence of the front and back bars and spaced therebetwo snbsf'ribing witnesses.

tween the portions of the vertical bars between,the front and back bars being of lesser E "EOPGE n' RNI'HAR l .G width whereby to form shoulders for the' Witnesses:

purpose set forth. i '1`m:o.`WEmmn,

In testimony whereof I have signed my Hxln' Bzi'scnnNAUEn.
